Symptoms associated with Parkinson’s disease include tremor, muscle stiffness, and slowed movement that make it difficult to execute such simple tasks as holding an eating utensil steady, and patients currently have few options for relief outside of a hospital or clinic. Some medications can help, but over time they tend to become less effective. To give Parkinson’s patients another in-home option, a research team of Johns Hopkins University graduate students have invented a headband-shaped device that delivers noninvasive brain stimulation to help suppress symptoms.
